plusminus¶ ↑

This gem provides a way to calculate uncertainties of measurements.

5.129213.pm(0.01).to_s    #=> "5.13"

You can access the value and delta fields:

5.129213.pm(0.01).value   #=> 5.129213
5.129213.pm(0.01).delta   #=> 0.01

Error propagation is handled for operations

3.2.pm(0.1) + 4.5.pm(0.1)
# => 7.7.pm(0.2)
3.2.pm(0.1) * 4.5.pm(0.1)
# => 14.4.pm(0.77)
